Participants

Reaction Steps

To methacryloyl isocyanate (5.55 g; 50 mmol) in dichloroethane (15 ml), a solution of o-fluoroaniline (5.55 g; 50 mmol) in chloroform (30 ml) was dropwise added. After completion of the addition, the precipitated crystals were collected by filtration. From the filtrate, the solvent was removed by evaporation under reduced pressure. The residue and the crystals were cobmined together and recrystallized from benzene to give N-methacryloyl-N'-o-fluorophenylurea as colorless needles. M.P., 155°-157° C.
